This invention relates ,to metallic telephone booths .and more particularly to metallic telephone booths ofthe stall type.

.The object of the invention is to improve the construction of such telephone booths and reduce their manufacturing cost. i *f According to the present invention, a metallic booth is provided leaving corner posts constructed of metallicsheets clamped to each other and held in spaced rectangular relation by angle bars secured to these corner posts a suitable distance rom their lower ends to iormvsupporting means for the side wais and the rear Wall c-f the booth, while the comer-posts at the front of the booth are held in adjusted spaced relation to each other at their upper ends a spacer member forming a portion of the iront wall, other trent Wall portions beingr secured to the front corner pests to Aform in cooperation Frith the spacer members at the top of the ooo-'3h' the entrance of the booth.

A roof plate 'which has one of its edges secured to the' .spacer er and its opposite edge to means carried by the rear corner posts at their upper ends serves to hold the rear corner posts in spaced relation to each other and these corner posts in spaced relation to the front corner posts, the roof plate also ser ing for securing a ceiling to form therew 'i a easing for housing soundrong material, the roof plate cooperating with the spacer at the top front end of thebooth, with a v-:all of the ceiling and e. diagonally disposed plate secured to the spacer member to form a compartment for a lighting fixture, the diagonally disposed plate being removable to give access to the lamps of the h htng fixture troni the interior of the booth. A plurality of means in the form of channel shaped elements which are secured to the roof plate and to the ceiling serve as conduits for the lead-in telephone and lighting fixture wires While reenforcing the ceiling along its longitudinal edges. A plurality of molding strips cooperate with portions of the corner' posts and screws engaging these corner posts to form clarnpi ing means for securing the side Walls and tne rear wall in adir-tied relation to each other on the mounting trarne thus formed. Assemblies of intertting box :d apsrtnrecl cover-like elements form the side l', the rear wall and the front wall for the o h, such assemblies forming ccntainers for lio'.:s"^ s@and-procing material, while the sections placed at the'lower ends of theside walls, the rear wal; and the cover and box elements which form the front wall sections are packed with fibrous material servir;y as fillers f orsupporting pressures tending to deform the (cil lss-2)' f I box and cover-like elements of these wall sections.

Other novel'features and advantages of the invention will appear from the following'dcscrip.

The telephone booth of the invention which, as

shown in Figs. 1 and S, is of rectangular cross section consists of four corner posts Ci, C2, C3

and C4, each formed of two metallic strips I9' and H. The metallic strip H is bent at right angles with its edges bent inwardly substantially 130 degrees in overlapping relation with the op.-

posite longitudinal edges of strip lo, the latterbeing bent at a number of points to form abuttingr portions for the edges of the booth wall and with a portion disposed. diagonally relative to the abutting. portions for receiving a plurality of equally spaced screws i2 erving for securing the booth Walls to the frame in a manner which Will be hereinafter described in detail. s

The corner pests Cl, C2, C3 and C# thus constructed are held in spaced relation to each other at a distance of substantially the total height of the booth from their lower disposed ends by angle bars t3, l-i and i5, best seen in Fig. 8, the side bar l3having its ends secured as by welding to comer posts Cl and Ci; while the side bar i I4 is secured at its ends to corner posts C2 and C3 and the rear disposed bar l5 is secured at its venclsto corner posts C3 and C-i.

Diagonally disposed metallic strips such as i5 and il shown in booth` shown ri l The plete E# cooperates with the wall N ofthe of angle bars i5 with angle bars i3 andv I4 for reenforcing the booth t these points, while rer-' V ticaily disposed plates such as PI, P2, 153 and-P4' are fitted diagonally to' the' corner posts Cl, C2, C3 and C4 and secured thereto by ai plurality of similar screws SC shown in Figs. 1, 5. 6 and'f.

.while to the lower end of corner posts Cl, C2, C3 and C4 are welded the plate BPI, BP2, BPS and BPS, respectively, serving as bearing points for the booth. x

Th;l front corner posts Ci and C2 are held in. adjusted relation to each other at their upper disposed ends by a channel spacer member 2l) .best seen in Figs.'1, 2, 3, 5 and 8 Welded thereto at beth ends. To the top end of each of the rear corner posts C3 and Cd, as'shown in Figs. 3

. and 5, there is secured as by welding a. plate 22 cooperating with the spacer member 2) for supporting a roof plate 25 shomi in Figs. 3, 5 and 8, this roof plate being held securely to the plates 22 bv a number of screws 23 while at its iront end the roof plate is secured by the spacer memoer 2O by a number of screws such as 25' passing through clearance holes in the roof plate 25 for erigev ng threaded holes 2l in the spacer 2 thus serving to hold the corner posts Ci, C2, C3 e'-fi'C4 in adjusted spaced relation at the-top end ci the booth.

To the underside of roof plate 25 there is secured es by Welding along their length, the substantially U-shaped bars 2S and 2l best seen in Fiss. 3, 5 and 3, the 'oar 21 serving as a conduit for the lead-in wires of the telephone apparatus in the form of a coin collector TA shown in Figs. 1, 2 and 4, while the bar 2B serves as a conduit for the lead-in wires of a lighting fixture 28 shown in Figs. 3, 5 and 8, provision being mafie for passing the lead-in Wires of the tele- Anone apparatus and the lead-in Wires of the "biinr fixture through the openings l5, 'I8 in roof plate 25 and through openings in nsuleting plates Yi and Y2 which are in turn secured to the roof plate 25 vby a number of screws YZ. To the outer disposed side of oar conduits QG-nd 2l' there isv secured as by welding the longitudinal wall portions of a box-like shaped ceding made of a thin apertured plate 23 which cooperates with the roof plate 25 to form a casing for housing fibrous material SP such as rcel: wool inserted between the roof plate 25 and tbe ceiling plete 29 prior to the welding of the plate 29 to the bar conduits 2S and 21 thus formin: a sound-proof roof and ceiling of unit construction, f

A bracket 60 which is secured'as by welding to the inner sire of the spacerv member 2:] supports a lamp secket- El and a lamp reflector 28 extending in juxtaposition to a translucent glass E3 closing en opening in a plate Ed secured along vcme of its longitudinal edges to the lower edge of spacer ser 28 as by a plurality o1' screws 65, While r lcnsitudinal edge of plate 64 is bent to reir er with the angle formed by ceiling 23 am! its front-disposed .rall V as shown in g 5.

. is formed ofa'box-'xike element 30 and a. corel'- f celving, Vfor example, a. plurality of cardboard :i
